COVER-FEEDING MEANS.

Original application filed October 25, 1923, Serial No. 670,682. Divided and this application filed December 24, 1924.

This invention relates generally to blank feeding devices and has more particularly reference to a device for feeding covers or bottoms from a stack to a seaming mach ne. This application is a division of application Ser. No. 670,682 filed October 25, 1923.

In the accompanying drawings the invention is shown in a concrete form in which:

Fig. 12 is a detail sectional view on the plane of line 12-12 of Fig. 11.

1 indicates a body or container to which a cover or bottom as 2 is to be united. As shown in Fig. 11 the bodies come down an inclined plane 79 and are received by a dial 80 which delivers them to pockets 24 of a rotatable turret 11. Bottoms 2 are contained in a stack 84 from which they are separated 40 and carried by suitable means to inclined dial 104 which latter conveys said covers by means of fingers 144 and turns them edgewise into guide 145, from which they pass to pockets 25, adjacent pockets 24, in the turret. Suitable mechanism, not here described but generally indicated by reference character 4, unites the bodies and covers. Suflice it to say that the bodies and covers are clamped by suitable work-holding means in the turret and that a number of bodies and covers are acted upon at the same time during the revolution of the turret in the Serial No. 757,818.-

manner described in application Ser. No. 670,682.

84 indicates a hopper for the covers at the lower open ends of which are a plurality of feeding-out rollers 85 (here three in number) having spiral grooves 86 in their outer circumference. These rollers serve to support the stack and also, by their rotation, to (:0 feed out the covers singly in "a manner well understood until the cover drops on table 87 between the arms of starwheel 88 which conveys it out of the plane of the hopper. Each feeding-out roller 85 is carried b an up- 05 right stem 89 suitably supporte in the framework and each stem carries a pinion 90 engaging a central gear 91 also mounted in the framework. One of the pinions 90, marked 90, drives gear 91 and the latter in turn drives the two other pinions 90. Pinion 90 also drives starwheel 88 by means of pinion 92 engaging internal gear 93 on said starwheel. Gear 90 receives its motion from pinion 94, loosely mounted on upright shaft 95, by means of pins 96. Pinion 94 is driven by gear 97 and moving with the latter gear is pinion 98 imparting motion to a train of gears 99, 100, 101 and bevels 102 and 103 by means of which latter inclined so dial 104 is driven. Gear 97 and pinion 98 are slidably mounted in the bushing or actuating member 105 so that an upward movement of these parts will disengage gear 97 from gear 94 and pinion 98 from gear 5 99 thereby stopping dial 104, starwheel 88 and feeding-out rollers 85. Fixed to the underside of pinion 98 is one or more cam dogs or teeth 106 that are engaged by corresponding cam dogs or teeth 107 on rotating clutch member 108, said rotating clutch member being seated in stationary member 109 carried by the framework. It will be evident that, if any part of the cover feed mechanism 'ams and the parts stop rotating, dog 107 will lift pinion 98 and gear 97 by reason of the inclined surfaces on dogs 106 and 107 and thus stop rotation of the parts of the cover feeding means. When this happens, handle 110 will be moved downward by turning on center 111 because handle has two arms 112 that engage in groove 113 of the sliding member carrying pinion 98 and gear 94. Thereupon latch 114 will fall and will retain the parts in the position to which they have been moved, and the cover feeding mechanism will be stopped until released by hand. Clutch member 108 is driven from gear 115 by means of clutch pin 116 seated in member 108 and normally pressed by spring 117 into an opening in member 118 which latter is carried by gear 115. Gear 115 is driven from gear 119 mounted on shaft 120 carrying gear 23 which latter receives its. motion from idler 22. If clutch pin 116 is with drawn from engagement with member 118 rotation of the parts of the cover feeding mechanism will cease. To accomplish this the following construction is used: Pivotally mounted on stationary member 109 at pivot point 123 are two arms 124 carrying trip lever 125 and having also two pins 126 that normally enter openings in reciprocatory dogs 127 mounted in slides 128 of stationary member 109. Springs 129 bearing on member 109 and connected to said dogs 127 urge the dogs inwardly but the inward movement is prevented by pins 126. When trip lever 125 is lifted, pins 126 disengage the dogs and these fly inward and one of the cam surfaces 130 thereof engages cam surface 131 of clutch pin 116 when the latter comes opposite one or the other of said dogs 127 with the result that the clutch pin is lifted and power is no longer transmitted by gear 115 to member 108 and the cover feeding ceases to operate. Member 118, however, continues its rotation and restoring cams 132 carried thereby act on rolls 133 of dogs 127 and retracts said dogs thereby allowing spring 117 to restore clutch pin 116 to engagement with member 118 and pins 126 descend into engagement with the dog and hold them in their restored position. The driving connection is thereby reestablished. Any suitable means may, of course, be used for lifting and lowering trip lever 125 and it may be done by hand but, in the present instance, the trip lever is controlled from the can body in feeding mechanism by the following means: Supported in front of body infeed dial 80 is a detector arm 134. This arm is pivoted at 135. So long as bodies 1 pass 1n a constant stream this arm is held outwardly by said bodies but if a body is missing it falls inwardly by gravity. Connected to this detector arm is one arm 136 of a bell crank,hung on rod 137, the other arm 138 of which is secured to connection 139 which latter extends to and is secured to one arm of a bell crank mounted on bracket 141 the other arm 142 of which comesunder trip lever 125. When, therefore, a body is missing trip lever 125 is lifted, the action being facilitated by spring 143, and the cover feeding mechanism is stopped, and when a body is again fed the cover feeding mechanism starts again.

A cover is separated from the stack by roller 85 and is thereby fed to the starwheel This starwheel carries the cover to fingers 144 of inclined dial 104 which conveys the cover and turns it edgewise into guide 145. From guide 145 the cover passes into groove 25 of one of the pockets of the turret where it is then associated with a body in the manner previously described.
